Senator BOB BROWN (Tasmania—Leader of the Australian Greens) (14:24): My question is to you, Mr President. I refer to the motion of the Senate three months ago that called on the parliament to join the Do Something! energy efficiency campaign, 'The 10% Challenge', and reduce energy use in Parliament House by 10 per cent. I ask, Mr President: could you tell the Senate what action has been taken to carry through with that motion?
